First off let us disclose that these are recommendations for installing newer wheels on older cars and newer Porsche cars from the early PORSCHE 911 SC, 944, 951, 928, 986, 987, 964, 965, 996, 997, 991, Cayenne, Panamera and GT-cars. There are by no means for us to state facts on every car that was produced. We will continue to update this page as time permits. The recommendations are made from cars we have personally installed. This information is provided based on our experience for wheels we offer on this site. It is very important to understand that some wheel & rim manufactures used different off-sets, back-spacing, center-bore, lug-seat and back-spoke clearances. This will usually range from manufacture to manufacture and that is why it is important to know who you are buying from to ensure prior fitments have been made. “ask for photos” We are familiar with the wheels we offer and make this information based on that information alone. We cannot speak on behalf of a wheel we have not performed installation clearances and checks on.

WE DO NOT PROVIDE FITMENT ADVISE OVER THE PHONE"In all fairness please refrain from calling our sales desk to ask fitment questions from purchases made elsewhere", we'd like to help but cannot interrupt or tie up the phone lines for our customers. If you have a general fitment question please E-mail us so we can try and answer your questions. We usually reply within the first 24 hours so please be patient, however we may refuse to offer advise on other aftermarket wheels since we may not know the back-spoke clearance. info@wheeldynamics.com There are many wheels and plenty of sizes and offsets that came from the factory. Some wheels are not approved for certain models because the wheel and tire technology was not in use when these cars were made. We believe the single most improvement on your car for performance can be the right wheel and tire set up. It not only will improve handling but also braking when updating your car to the latest wheel and tire set up. It is just like playing basket-ball with an old set on Converse Chuck Taylor's. The shoes have little to no support and about the same on the sole. As soon as you slip on a new pair of Jordan's you realize how shoes have improved. It is the same with your wheel and tire set up. Porsche is moving to larger and larger wheel diameters for numerous reasons. Back in the 80's 16" wheels were the state of the art now Porsche has moved all the way up to 21” diameter wheels. We understand that some shops who are unfamiliar with the Porsche cars have used this information to assist them with installing wheels on Porsche cars, please DO NOT RE-POST, COPY OR RE-DISTRIBUTE THIS INFORMATION, IT IS INTENDED FOR THE EXPLICIT USE OF WHEEL DYNAMICS & VISITORS FOR REFERENCE ONLY. Redistribution or unauthorized use of this guide is strictly prohibited.

FINDING THE RIGHT INSTALLATION CENTER / CENTREA lot of our customers tell us that they chose to have us sell them tires for their Porsche cars because they do not have a trusted installation shop that they can trust to provide services such as we do. We offer tire installation using an Italian made Corghi & a Porsche dealers choice Hunter, we also use the industry standard Hunter 9700 Road Force balance as well as provide our customers with Nitrogen inflation. Our recommendation if you chose to have your tires installed locally might be to search through the Hunter shop-locator, here you can find those who have invested tens of thousands of dollars for the best equipment for their shop: CLICK HERE

BalancingWe recommend when it's time to balance your wheels that you find a shop that not only has good equipment but the right adapters (cones & locking plates) in order to optimize your balancing services. Not all shops will have these adapters so you might need to make several calls to locate one. Below we have included photos showing the correct adapters for balancing, these adapters are crustal in order get your balancing just right, without them you are not getting the very best balance available. You'll note that using the right equipment will allow your wheels / rims to mount on the balancer at the same points as they do on your Porsche. See the included photos below.

Take a look at the photos on the left, CLICK ON THE PHOTO it will then open up so you can read more information. The purpose of this plate with the "fingers" is that it simulates lug bolts as it mounts on your vehicle so it should also mount on the equipment to balance your wheels. You will also notice the cones, it is EXTREMELY IMPORTANT to take note of how the cone needs to mate with the wheel, this will ensure that your wheels / rims are balanced on the machine in the same manner that they are to be mounted on your Porsche.See the included photos below for a clear understanding of why each is important.

THE PORSCHE 997.1 (2005-2008) 997.2 (2009-2012) 911 Produced from 2005-2012 This Porsche 911 (997) gave way to more space in the rear allowing for wide track wheels such as the 11" & the 11.5" wide rears to be used. The standard 19" wheels now offered can in a 19x8 (et 57) and a 11" (et 67) but also offered the 11.5 option. What makes this vehicle wheel options easy is that most owners can now purchase after-market 19" wheels and use their existing tires. TPMS was also installed starting in 2006 make sure your sensors are transfer-able. Wheel Dynamics wheels are all tested and compatable with factory TPMS equipment. The 997 S models to require a little more room for the back-spoke clearance due to the larger brake system. Turbo and C4S models typically use the rear 19x11.5 (et 51) or the 19x11 (51), same front sizes on all models. You can easily fit the 19x11 using 40-55 et. Turbo/C4S 19x8.5 (45-50) and 19x11 (et 50-70) (you can option for up to 12" fitment but may need to custom order those wheels)

THE PORSCHE 996 (911 Produced from 1999-2004)911 Carrera 99-01 & 911 02-04 (AKA 996) (Also GT3)This Porsche 911 (996) has an early version and a late version plus a wide body. The Porsche 996 comes from the factory front 7.5" or 8" wheels with a 50mm offset.. The Porsche GT2 & GT3 will have a 18x8.5 offset 40mm front. The rear narrow body 996 C2 & C4 is typically come with a 18x10 offset 65mm or 17x9 off-set 55. The early production 1999-2001 Porsche 996 models have less fender-clearance over the later 2002-2004 996 Porsche C2 & C4 which have around 10-mm more space on the out-side edge.

If you wish to install an 11" wheel on the early production 911 (996) Porsche then we would suggest rolling your rear fenders to fold up the fender edging. The later production 996 Porsche was rolled in the rear by the factory which gives you more room allowing you more space to play with. After-market wheels you can easily run a 19x8.5 wheel and 19x11 (when using the right off-sets) without any issues, however there are some who want to go with an 18 or 19x11 which may require a narrow tire, neg-camber or keeping away from lowering the Porsche all together. The factory 997 wheel in 19x11 offset 67mm will need a small spacer in the rear with some tires. The 2002 and up cars do not have this issue as the track was slightly widened. GT3 is 18x11 offset 63mm. With these models you can easily run a 18 or 18x8.5 front (et 45-55) and rear 18 or 19x11 (38-50). VEHICLE LOWERING AND FENDER ROLLING but will still be quite aggressive if you decide to use 52-et 11" rears on early productions 1999-2001. The Turbo and C4S models do come with a 18x8 (et 50) & 18x11 (et 45)::: You can easily run 19x8.5 (45-50) & 19x11 (38-51)

No spacers needed for newer17"- 18" wheels in the 48 mm-65mm et range. All 986, 996, 997, part# wheels will require a 1/4" (7mm) for the front hub. This is so the wheels will mount flush on the hub. This is needed for all newer wheels. 993 part# wheels will not need the spacer.

Most extreme fitment-Front 18x9 et52mm -Rear 18x11 et65mm

Below 1987-1991 seen 19x8.5 (45) & 19x10 (48) Keep in mind that 951 (Turbo S) models have just a touch more room in the fnder line due to factory rolling, this can easily be done to get this set up to work on most 944 non-Turbo S models. When outfitting the 944 with 8.5" wide fronts you will need to roll the fenders some and should use tires no wider than the 235/35/19 unless you do some aggressive rolling.

PORSCHE 928 1978-1985

Can use all of the narrow body wheels from 993-986-996-997 50mm -65mm et front and 48mm - 65mm et rear. 1981 to 1984 cars have 21mm spacers in the rear. These can be removed to fit some wide body wheels. (18x10 40mm 18x11 45mm) You may still need to do some fender mods depending on the tire size.

Most extreme fit 18x10 et65mm front and 18x11 et45mm-63mm. The 18x11 et63mm wheel fits nicely on the rear with a 285/30/18 tire. 19"s fit very nicely on the car

18x8et 50mm and 18x11et 45mm below

PORSCHE 928 1986-1991 If you play to use stock wheels you can use all of the narrow body wheels from 993-986-996-997 50mm -65mmet front and 48mm-65mm et rear. Some manual 89GT cars have 17mm spacers in the rear so you may have to chuck them when using wider wheels and tires

Most extreme fit 18x10 et65mm on all four corners. The 18x11 et63mm wheel fits nicely on the rear with a 285/30/18 tire. 19"s are possible 18x8et 50mm and18x10et 65mm below (factory wheels shown).When selecting an after-market wheel you must understand that these cars will have minimal clearance on the front hub so your wheel selection has to conform to a deep enough center-bore or some small spacers might be needed.
